replacement O2 Sensor - All 1 wire not 3?

[DSBall]

I have a 95 GMC Yukon 5.7 liter Gas and the o2 sensor is a 3 wire setup. All the replacement o2 sensors are only 1 wire?

Then you're getting the wrong sensor somewhere. A 1-wire sensor is not a heated o2 sensor.

Thanks, I have even looked them up and Bosch and Denso web site and get the same thing. I will try an OEM from my local GM dealer and see what I get.
